- HORSESHOE.

SPECIFICATION forming part of Letters Patent No. 609,132, dated August 16, 1898.

Application filed September 22, 1897. Serial No. 652,572. (No model.)

To all whom it may concern.-

Be it known that 1, ROBERT S.WIESENFELD, a citizen of the United States, residing at Baltimore, Maryland, have invented certain new and useful Improvements in Horseshoes, of which the following is a specification.

My invention is an improvement in horseshoes, and is designed to provide a shoe which a is always rough.

The invention includes a horseshoe having a channel on its under face with a series of projections of varying height within the channel, so that as one set of projections wear down another set will come into play, and so on until the shoe is worn so thin as to require to be replaced in case the projections are integral with the shoe; but the invention also contemplates making the projections on independent plates adapted to be inserted within the channel of the shoe and secured therein, and in this case as the projections wear the plate may be removed and other plates inserted, and this indefinitely extends the life of the shoe.

The invention includes details of construction more particularly hereinafter described.

In the drawings, Figurel represents a bottom view of the shoe. Fig. 2 is a like view of a modification. Fig. 8 is a like view showing the projections on detachable plates. Fig. 4 represents a view of a special form of fastening device for the detachable plates of Fig. 3. Fig. 5 is a View of an additional fastening device for detachable plates; and Fig.

6 is a view of the detachable plate having projections on one side fitting recesses in the wall of the shoe, so as to aid in holding the plates in place.

In the figures the shoe is shown as of the usual shape, and I make it with a channel or groove on its under face, as at a. In one form of my invention I locate in this channel a series of projections made integral with the shoe, the projections being of different heights, as shown at b, c, and d. The shoe is provided with heels and a toe-piece of the same height as the highest projections, and it will be seen that as the heels and toe and the highest projections 17 wear down the second series of projections a will come into play, and after these are worn down a third set cl will present a rough appearance, and so the shoe will always be rough and present points or projections adapted to prevent slipping.

As shown in Fig. 1, the series of projections extend across the channel, but are of less extent than the width of the said channel, and in order to prevent clogging by snow and ice the channel may be provided with a filling of rubber, which, while keeping the projections free from obstructions, will read ily permit the penetration of the points under the pressure of the weight of the horse.

I do not wish to limit myself to the particular arrangement of the projections shown in Fig. 1, as I may, as shown in Fig. 2, arrange some of the projections so as to extend lengthwise instead of across the channel.

As shown in Fig. 3, instead of making the projections integral with the shoe I may make them integral with base-plates 8, arranged in sections and insert these sections in the channel of the shoe and secure them removably therein by screws or otherwise, so that as the projections wear down the plates may be removed and replaced by others, and thus extend the lifetime of the shoe indefinitely.

I'wish to call special attention to the fact that by making the shoe with "a channel in which the projections are located the walls formed by the channel add to the roughness of the shoe and at the same time prevent the rapid wear of the projections.

As a convenient means for holding the baseplates containing the projections securely in the bottom of the channel I provide screws, as shown in Fig. 4, adapted to enter holes in the bottom of the channel, these screws having split upper ends adapted to pass through openings in the plates 6 and then to be bent over, as shown in dotted lines, to hold the plates in place.

To further secure the plates, I use strips of metal, as shown in Fig. 5, which are adapted to be passed through openings in the walls of the channel above the line of the plates e, and the ends may be turned up or bent upwardly or downwardly into countersunk recesses in the walls of the channel, thus preventing the IOO wise fastened, I provide projections from one edge, as shown at Fig. 6, adapted to enter recesses in the adjacent wall of the channel.

What I claim is 1. A horseshoe having a channeled under face, the walls of the channelbeing continuous, and a series of projections extending frolnthe bottom of the channel and arranged radially between the Walls thereof, said proj ections being of greater height than the walls of the channel and of less extent than the width of the channel, substantially as described.

2. Ahorseshoe having a channel on its under face, a series of projections extending across between the walls of the channel and projecting from the bottom of the channel, and a series of longitudinally-extending projections alternating with the lateral projec tions, substantially as described.

3. A horseshoe having a channel on its under face, a removable plate or plates therein, and a series of projections extending laterally of said plates, with means for holding the plates in position, substantially as described.

4. A horseshoe having a channel on its under face, a removable plate or plates therein, a series of projections .carried by said plates, and holding means for said plates extending from the bottom of the channel, and supplemental holding means extending betwejenthe walls of the channel above the removable plates, substantially as described.
